Full Job Description
The Role

We're hiring a Sr CSM to own our brand relationships from the first day of onboarding through renewal and expansion. You'll be the person brands trust to make Checkmate work for them: live fast, revenue early, and strong first results that turn into long-term partnerships.

This is a high-ownership role on a small team. You'll carry your own book of brands, run those relationships end to end, and own the revenue we deliver to brands. If you like owning outcomes, moving fast, and being the reason a brand stays and grows, you'll thrive here.

What You'll Do
  • Onboarding & Activation
    • Lead onboarding for new brands, from kickoff through go-live
    • Configure each brand's offers, channels, and audiences for their goals
    • Set success metrics and a clear first-30-days plan with every brand
    • Get brands to first revenue quickly and cleanly
  • Account Management
    • Own a book of brands as their main point of contact
    • Run regular check-ins, business reviews, and performance recaps
    • Track account health, usage, and renewal timelines
    • Get ahead of risk before it reaches a renewal
  • Retention & Growth
    • Own renewals across your book
    • Identify expansion opportunities and build the case with data
    • Turn strong results into case studies and references
  • Cross-Functional Execution
    • Work with Rev Ops to translate performance into account actions
    • Bring brand feedback to Product and Ops, and flag what matters
    • Partner with Sales on clean handoffs and account planning
  • Build for Scale
    • Help standardize onboarding playbooks and account templates
    • Improve CS workflows and reduce manual steps
    • Contribute to repeatable processes as the team grows
Why This Role Matters

Brands come to Checkmate for incremental revenue. You're the person who makes sure they get it, and that they stay to get more. When your brands are live, growing, and renewing, the whole business compounds. This is one of the most direct lines to revenue we have, and it's yours to own.

Requirements
Who You Are

What You Bring
  • 4+ years in customer success, account management, or partnerships in martech, ecommerce, or SaaS
